tRESETFLT spec max of MC33771

[MatsunagaHitosh]

MC33771x datasheet specifies RESET deglich filter time as tRESERFLT 100 us (typ).

Could you confirm maximum deglitch filtetr time?

It is important to specify RESET pulse wideth which will not to fail RESET.

Best Regards,

Hello Matsunaga,

The maximum deglitch filter time for the MC33771x is 1 ms. This means that the RESET input must be held low for at least 1 ms in order to guarantee that the device will reset.

The RESET pulse width must be at least 100 us in order to guarantee that the device will reset.

Here is a table from the MC33771x datasheet that summarizes the RESET input requirements:

Requirement Value

RESET input minimum level	0 V
RESET input maximum level	3.6 V
RESET input pull-up resistance	10 kΩ
RESET input deglitch filter time	100 us (typ)
RESET pulse width	100 us (min)
